I know the story, actually a very good one. But don't have the title in my mind or the book at hand, will check later at home.
There where two types of immortality. One was the teleportation thing the other one was a "gene therapy" done to kids who where then stuck in 12 - 14 year old bodies.
I'm pretty sure you're talking about the Ringworld series, especially the later books.
Proofed it quickly and missed "prey instead of pray." WHACK!!! Another slap on the wrist.
I thought that that was intentional. Way cool if it had been.
I agree there unfortunately. I did the math a few years ago, during which time the electric price hasn't really risen substantially in the midwest. I basically figured that the cost of installing the PV panels would be recouped at about the same time that the panels reached about 30% of their original capacity... in other words by that point you'd be so close to replacement time that it was almost a wash. It just didn't make sense to me because when I also included costs of routine maintenance (you have to clean PV shingles or panels frequently to ensure maximum efficiency) it really was a net negative.
Now, if electricity prices were higher like in Australia then I could definitely see it making a lot more sense.
Where did you get these data? I can't even find any timetable for solar panels degrading to 30% rated capacity. The typical warranty is no worse than 80% of rated capacity after 25 years.
Doing a little math: Normal degradation is around
The biggest appeal was getting into the chat system. There, we could chat with what I assume were Darthmouth college students. "JOIN XYZ" I think was the command from the main menu.
There was this cool VT display of who was in the chat, so you could tell how many people were there. I used to chat with these people all the time. It was great for a precocious 13 year old who couldn't talk with his peers because his vocabulary and worldview was greatly expanded from theirs. How unfortunate that my social skills were so backward at the same time.
The details are a bit foggy, but I'm sure with some conversation with some of the same folks who used to chat there, I could dredge up those memories. Anyone remember chatting on that system?
Oh yes. I was a freshman in '80, and I spent a lot (too much?) time in Kiewit, playing the adventure game, writing programs in BASIC (and later BASIC7, which had a multi-threaded version if you can believe that) chatting on XYZ. Probably talked to you at one point.
BTW, it's 'Dartmouth'. I'm not fussy, but I'm sure there are alums who are.
The average kwh cost in the US is about twelve cents, or $0.90 to $1.20 to go 25 miles.
PG&E has standard rate plans that vary from 11c/kWh (which is so little that you can't afford a refrigerator) to 30c/kWh. There are also special plans (time- and season-driven); one of them is specifically intended for charging EVs. In that plan, IIRC, the rate is about 5 c/kWh - but that is at night only. I do not recall what is the rate during the day. Utilities hide the actual rate tables. PG&E has a convenient calculator. I tried it with Tesla S60 and 60 miles per day. I got about $150/mo on plan EV-A.
60 miles per day * 30 = 1800 miles per month. If we convert this to a gas car, $150 pays for about 42 gallons of gas. This results in efficiency of 42.85 mpg. This not something to write home about. My own Prius does 52 mpg on flat land, and 45 mpg if you add climbing of the surrounding hills. If these calculations are correct, it is not efficient to use an EV even if you got it for free. At best it equals the hybrid that costs a third of the price of the EV.
I'm not sure I understand their math. A Tesla 60 gets at least 3 miles per kWh (http://www.teslamotors.com/goelectric#range), so your 60 mile day would take about 20 kWh. At 5 cents per kWh, that is $1/day, so about $30/month. To get a cost of $150/month would take electricity at $.25/kWh. At $.05/kWh, you end up getting more than 200 miles/gallon equivalent, and that's if gas is $3.57/gal. Around here (Bay area) it's closer to $3.80. Like I said, the math is squirrelly.
Do you know what de facto means?
Well, I know what everybody says it means, but not necessarily what the rules say it's supposed to mean.
Man, I wish I had mod points... that's beautiful.
So if I set up a print shop that prints and sells copies of recent bestsellers and sells them dirt cheap to bookstores that sell them at deep discounts to consumer's that's a misdemeanor? How about if I download copies of the latest movie releases, burn them to DVDs and ship them all over Europe?
Then you would no longer be a private citizen but would be engaging in business. I think that almost everyone agrees that anyone who does that for commercial gain should have the book thrown at them.
Better not copy "Lord of the Rings" then...
"We're about ready to load our new destination into our GPS and head out onto the open road."
It seems Mars has GPS aswell. Time to start Geocaching on Mars...
I know it's obvious, but wouldn't that be "areo-caching"?
But I'd bet the Chinese are considering mining operations off planet
I find the above quote a little bit too ironic
Speaking of mining and ores, I find yours a bit... (how to put it?)... pun-ic?
And 'ores' rhymes with 'wars'. Nice.
Indeed. You can't stress that enough. The part of labwork I hated most was working with Tritium-labels. Sure, that plastic shield holds back all the alphas, but stuff gets aerosolized and that is not particular fun.
I saw what you did there...
All the harry dresden books, for example, decided to be in a bold fond in the version I downloaded. Makes purchasing them a LOT more worthwhile (which I ended up doing for the first few, until I decided to give up on the series, but that's another story).
I saw what you did there...
Ah, the memories! Here are some of the stories I've heard and or witnessed over the years.
Hey, I have a similar story from when I was working at Dartmouth College in the mid-80's. I was on third shift with two other guys, one who knew what he was doing, and one who was, uh, not fully technology-enabled.
For some reason, one night the latter person thought it would be a good idea to clean out the cabinet of our Honeywell mainframe. With a broom. A long-handled push broom.
This was on a weekend, when we normally do a full backup (onto good old 9-track tapes), reboot the system into protected mode, verify the system integrity, and go into multi-user mode. Well, we finished the backups, and tried to reboot. Nothing was working, and the diagnostics were wonky and pretty uninformative, and we (the useful co-worker and I) spent an hour or so trying to debug what was going on. It wasn't until we asked the third guy about the machine that he mentioned his cleaning. The boot switches for the IPL were on the door, and when he was in there cleaning, the broom handle toggled several of them, leaving the machine in its unusual state.
Needless to say, we asked him to avoid cleaning mainframes with brooms in the future.
